6.3 ANALOG ADDRESSABLE LOOPS
Loop Control Module
(LCM)
Loop Controller for Loops 1,3 Max 2
Loop Expander Module
(LEM)
Loop Controller for Loops 2,4 Max 2
LEM “piggybacks”
under the LCM.
6.4 ANNUNCIATORS
ACM32 Annunciator 32 Red LED A maximum of 50
annunciators can be
connected to the
communications ring.
ACM16AT Annunciator 16 x Pushbutton inputs
16 x Red LED
16 x Yellow LED
SCS-8 Annunciator 8 x 3 Position switches
8 x Red LED
8 x Yellow LED
8 x Green LED
1 x Fire Trip (A/C) Reset switch
1 x Fire Trip (A/C) Activated/Latched LED
LDM-32 Annunciator 32 x LED outputs (Open Collector)
LDM-R32 Annunciator 32 x Relay outputs rated to 1A @ 30Vdc
6.5 FIELD MODULES
AZM-8 8 x AZF inputs (4k7 EOL resistor)
4 x Programmable Relay Outputs
A maximum of 100
field modules can be
connected to the
communications ring.
Larger/external power
supplies and separate
feeds are required for
systems with a large
number of modules or
long cable runs.
The RS485 signal is
regenerated at each
field module.
Fan Controller (FAN-C) 3 x Inputs (Opto-isolated, not monitored)
3 x Programmable Relay outputs
Note: AZM-8 and FAN-C field modules have been discontinued and will not be supplied for new installations.
When annunciators or field modules are powered from external power supplies, use a separate conductor to
connect the main power supply common terminal (-0V) to the remote power supplies common terminal (-0V).
